Detailed reference will now be made to the drawings, wherein like reference numerals identify like parts.

In FIGURE 1 a sliding window is indicated generally at 10, mounted within a frame consisting of upper frame member 11, side frame members 12 and .13, and sill 14. Mounted on sill 14 is extruded track 15 which supports stationary pane 16 and sliding pane 17 which is provided with handle 18. Also seen in FIGURE 1 is interior lower lock 1), interior upper lock 20. Shown in dotted lines are lower lock 21 and upper lock 22 which are located between the interior and exterior panes of this sliding window system, and act to lock the exterior sliding pane.

Turning now to FIGURE 2, track 15 is more clearly illustrated, as are interior panes 16 and 17, as Well as interior lock 19. Look 21 is also illustrated, as are exterior panes 23 and 24. Shown in interlocked relationship with window sill track 15 are stop members 25 and 26 and L-shaped in cross section, which abut against the ends 16a and 23a of panes 16 and 23 respectively, and prevent panes 16 and 23 from sliding in their seats in track 15. As is seen more clearly in FIGURE 3 stop members 25 and 26 extend from the ends 16a and 23a of panes 16 and 23 respectively, to side member 13 of the window frame. Referring again to FIGURE 2, stop 3 members 25 and 26 will be seen to be in interlocking relationship within track 15, lugs 27 and 28 projecting from stop members 25 and 26 respectively, being in slidable interlocking engagement in T grooves 29 and 3% respectively (see also FIGURES 6 and 7) in track 15. Similarly, lock 19 is in interlocking, slidable relationship with track 15, by means of L-groove 31, of track in which L-lug 32 of lock 19 is slidably engaged (see also FIGURE While stop members and 26, which are interlocked with track 15 prevent sliding of panes 16 and 23, support members 33 and 34 are also in interlocking engagement with grooves 54 and 55, respectively (see FIGURE 7), in track 15. Support members 33 and 34 serve to support panes 16 and 23 respectively and wall 33a of member 33 separates pane 16 from pane 17 when pane 17 is in open position, that is, when it has been slidably moved in the direction of arrow 35 of FIGURE 2. Similarly, wall 34a of member 34 separates pane 23 from pane 24 when pane 24 is in open position, that is, when it has been slidably moved in the direction of arrow 36 of FIGURE 2. As is illustrated in FIGURE 3, the ends of Walls 33a and 34a are bevelled at 33b and 34b, respectively, to permit panes 17 and 24 to slide freely by in track 15 as panes 17 and 24 are being opened. Support members 33 and 34 are illustrated more clearly in sectional view, in FIG- URE 5. It should be noted that support members 33 and 34 are identical in cross section to stop members 25 and 26, that is, of L-shaped cross section, and therefore the installation of a Window is greatly simplified as will be explained hereinafter.

Referring now to FIGURES 2, 4, 5, 6 and 7, track 15 is provided along its inner edge with a horizontal lip 37. The inner, or sill portion 38 of track 15 also senves as a support for interior lock 19, and terminates in a downwardly projecting wall 39 which has a pointed end having saw teeth 40 on 'both sides thereof. As is seen most clearly in FIGURES 2, 4 and 5 the portion of end wall 39 below lip 37 is adapted to be received in a groove cut in wooden sill 14, of slightly lesser width than the thickness of wall 39, whereby saw teeth 40 when pressed therein will prevent track 15 from being raised from sill 14. Track 15 is further provided. with a plurality of downwardly projecting support legs 41-,.;,adapted to rest on and be supported by sill 14. 2

As seen in FIGURE 4, upper window frame member 11 is provided with recesses 57 and 57a which act as upper tracks for sliding panes 17 and 24, respectively, and as upper seats for stationary panes 16 and 29, respectively. In addition, recesses 54 and 54a permit all four panes to be raised above track-15 during installation and removal of the panes as is well known in sliding Window installations. As is customary in sashless sliding window systems, recesses 57 and 57a will each contain a stop member (not illustrated) to prevent movement of stationary panes 16 and 23. In other words, the stop members in recesses 57 and 57a will act against the upper edges of panes 16 and 23 in the same manner as stop members 25 and 26 act against the lower edges thereof.

Track 15 is further provided with a serrated surface throughout its length in grooves 42 and 43, being the supporting surface for sliding panes 17 and 24, respec tively (see FIGURES 6 and 7). These serrated surfaces facilitate sliding of panes 17 and 24 when these panes are being moved from open to closed position or vice versa.

Turning now to FIGURES 8, 9 and 10, a lock according to the invention is illustrated. The lock includes a cylindrical housing 44 open at one end, and hollow cylindrical bolt 46 projects therethr-ough. Spiral slot 47 is provided in cylindrical housing 44, and projecting therethrough is handle 48 affixed to bolt 46 which is rotatable within housing 44 by means of handle 48. Contained within housing 44 and bolt 46 is spring 49, normally urging bolt 46 out of housing 44. It will be appreciated that rotation of bolt 46 by means of handle 48 in spiral slot 47 as to the position shown in broken lines in FIGURE 10 will partially withdraw bolt 46 into cylindrical housing 44, while rotation in the opposite direction will result in bolt 46 being forced forwardly out of housing 44 by the action of spring 49. Projecting from the front wall of bolt 46 is an axial extension or stop 50. Lug 32, integral with the front edge of base 45, is adapted to slidably interlock with groove 31 of track 15.

As seen in FIGURES 2 and 3, bolt 19 is free to slide between two stops 51 and 52 on sill 33 of track 15. In FIGURE 3 lock 1? is shown in solid lines abutting stop 51, and in broken lines in a position intermediate step 51 and stop 52. Lock 19, as has already been described, is in slidable interlocking relationship with track 15, lug 32 being engaged in groove 31.

As illustrated most clearly in FIGURES 2, 11 and 12, vertical channel members 56 are generally U-shaped in cross-section, although one of the arms of the U, arm 56a, is slightly longer than the other arm, arm 56]). Both arms 56a and 561) are slightly bowed toward each other, and both terminate in a small bead which runs the length thereof. A plurality of ribs 560 are provided on the interior of channel member 56 to ensure a weather tight relationship with pane 16 when pane 16 is in union with channel member 56 as illustrated in FIG. 12. Additionally, it will be noted that walls 56a and 56b of channel member 56 are pressed against both faces of pane 16, ensuring a weather-tight relationship therebetween. Wall 56a is of slightly longer length than wall 56b, for as is evident in FIG. 3, channel member 56 will be installed so that wall 56b is aligned with the inner edge of sill 38 of track 15, and the longer length of wall 56a of channel member 56 will ensure union with pane 17 as it is slidably moved to closed position, even though it might tend to wander slightly inwardly in its track.

Reference will now be made to FIGURES 13 to 18 which illustrate stop member 51, which is generally H- shaped in cross section and is molded of suitable plastics such as nylon. Stop 51 comprises cross bar 51a, spring arm 51b and pressure arm 51c. Spring arm 51b is generally curved and terminates in a bead at each end thereof. Pressure arm 510 is slightly curved in order comfortably to receive the finger or thumb of the operator during adjustment. Cross arm 51a is provided with a notch 51d which is located adjacent pressure arm 51c, and which results in the creation of a lug 51a in arm 51a, adjacent spring arm 51b. When stop member 51 is in locking position, as illustrated in FIGURES 14, 15 and 17, it will be seen that spring arm 51b is under tension in groove 31, between the inner wall of groove 31 and outer lip 31a thereof, with lug 512 being received within a slot provided in lip 31a, stop 31 thus being held in fixed position. Through manual application of pressure in the direction of arrows P of FIGURES 16 and 18, spring arm 51b may be compressed within groove 31 so that lug 51a is fully received within groove 31, and notch 51d comes into alignment with lip 51A of groove 31, permitting stop member 51 to be slidably adjusted in the direction of the arrows shown in FIGURE 16, along track 31. A plurality of notches in lip 31a, such as notch 31b illustrated in FIGURE 14, may be provided at the various locations at which stop member 51 is to be located, as will be explained hereinafter. As seen most clearly in FIGURE 14, stop member 51 will abut against base 45 of lock 19, to prevent sliding thereof beyond the point at which stop 51 is located.

The installation and operation of a window system 7 according to the invention will now be described.

The window to be fitted with a sliding window system according to the invention is framed according to normal construction practices. A section of track 15 is cut to the length of the sill of the window being fitted with a window, and a groove provided in the sill will receive pointed tooth wall 40 of track 15.

Before track 15 is affixed .to sill 14, stop members 25 and 26 are slidably engaged by lugs 27 and 28, respectively in track 15. Similarly, support members 33 and 34 are slidably engaged in the cooperating grooves of track 15. Stop members 25 and 26 will be .pre-cut to a length equal to the width of the window minus the width of panes 16 and 23, while support members 33 and 34 will be cut to a length slightly less than the length of'panes 16 and 23. Support members 33 and 34 will be positioned directly below the permanent position which panes 16 and 23 are to maintain, while stop members 25 and 26 will be positioned so that they abut the interior ends of panes 16 and 23 at one end, and side frame 13, at their other end. When the panes have been installed stop members 25 and 25 will of course remain stationary on track 15, as will support members 38 and 34. If desired a track reinforcing block 53 (see FIGURE 4) may be provided at the point where the lower lock 21 is to be installed. Lock 19 which is to slide in groove 31 of track is installed by simply cutting away a portion of lip 31a at either end of groove 31. T-lug 32 of lock 19 may then be pressed home into groove 31, where it is free to slide in groove 31, along sill 38. Two adjustable stop members 51 are installed in groove 31, one such stop member on each side of sliding lock 19.

Upper lock 20 which acts against the interior panes and upper lock 22 which acts against the exterior panes are then affixed as by screw nails to the underside of the top frame 11 in the positions indicated in FIGURE 1. Lower interior lock 19 is also aflixed as by screw nails or other suitable means to track 15, between exterior pane 24 and interior pane 17. Vertical moldings 53 are now placed in suitable grooves provided in side frame members 12 and 13.

Pane 23 may now be installed by firstly lifting it up wardly so that its upper edge extends into recess 57 provided in upper frame member 11 and subsequently lowering it so that it is seated on support member 34 and in abutting relationship with stop member 26. Sliding pane 24 may now be installed in a similar manner, so that it is supported by the serrated surface of track 15. Station ary interior pane 16 will be installed in a manner similar to exterior pane 23, and sliding interior pane 17 will be installed in a manner similar to sliding exterior pane 24.

With reference to FIGURE 3, interior lock 19 will now now be moved along track 15 until it is positioned as shown in solid lines. A notch 31b to receive lug 51a of stop 51 is provided on lip 31a at a point where base of lock 19 will prevent movement of lock 19 at the point where the shoulder of bolt 46 of lock 19 will press against the edge of pane 17. While lock 19 is in this position stop 56) will project beyond the end of pane 17, whereby pane 17 will be prevented from sliding within track 15, when lock 19 is in closed position. Further, the shoulder of bolt 46 will press pane 17 against pane 16 with sutficient force to prevent any rattling thereof. A second lock stop 52 will be provided on track 15, to prevent lock 19 from sliding beyond the point illustrated in dotted lines in FIG- URE 3. In other words, lock 19 is free to be slidably moved between stops 51 and 52 of track 15. A third notch in lip 31:: may be provided at a point intermediate the position of stop 51 and stop 52 illustrated in FIGURE 3, whereby a window may be left partially open, and at the same time be prevented from fully opening should an intruder attempt to gain entry through a window according to the invention.

When panes 24 and 17 are in closed position it will be appreciated that they are received within vertical channel members 56, insuring a weather-tight closure, and with all four locks 19, 20, 21 and 22 in locking relationship, the window is secure against weather and attempts of forced entry. As most clearly seen in FIGURE 4, bolts 46 of locks 19 and 20 press against pane 17 when in locked position, and stop member 51) project beyond the end of pane 17 absolutely preventing opening thereof.

When it is desired to remove the window panes for purposes of cleaning, lock 19 .is first slid from its normal position shown in solid lines in FIGURE 3 to the position shown in dotted lines, and pane 17 is then slid fully open. Lock 19 will then not interfere with the removal of pane 17 as it is lifted into channel 54 and swung inwardly and thus removed entirely from the frame. Similarly, panel 16 may be readily removed while lock 19 is in the position shown in dotted lines in FIGURE 3. Lock 21 will not interfere with the removal of pane 24 after pane 24 has been slid to open position, nor with the removal of pane 23, and therefore all of the panes may be readily removed for purposes of cleaning or the interchange of an exterior screen section for pane 24.

While all the locks are provided with interlocking lugs 32, only lock 19 need be slidable on track 15. Lock 20, 21 and 22 are afiixed directly to the track or to the upper frame member by screw nails or other suitable means.

The extruded track 15 as well as the interlocking sup port and stop members are of any suitable plastics, while the lock mechanisms are also of suitable plastics, as for example, nylon, including the bolt and the housing.

A number of small unobtrusive drainage holes to re ceive condensation may be provided at any convenient point in track 15, along with one or more small exterior drainage holes at the bottom of the exterior wall 41 of track 15.
